Looking to give your 7-speed 722.9 transmission a little boost? The Weistec 722.9 Transmission Pan is here to help! This innovative pan offers several benefits that can make a noticeable difference in your vehicle's performance.
First off, let’s talk about fluid capacity. With an increase of 2.5 quarts, you’ll find that your transmission can handle heat much better. More fluid means it takes longer for temperatures to rise, giving you peace of mind on those long drives.
But that’s not all! The pan features integrated cooling fins both inside and out, which work tirelessly to keep the fluid cool while you’re cruising down the road. Plus, there are two -8 ports that allow you to install an additional transmission fluid cooler, perfect for those who want to maximize cooling performance.
We’ve made maintenance a breeze with our handy "Fill" and "Drain" plugs. Unlike the factory pan, which only has a single fill plug (and requires you to remove the entire pan to drain), the Weistec pan allows for quick fluid changes. Just remove the "Drain" plug, and you’re good to go!
The "Fill" plug works just like the original Mercedes filling procedure, ensuring a smooth transition for your transmission fluid.
